ET's Leanne Aguilera spoke with one half of the comedy duo, Jemaine Clement, at FX's Television Critics Association press day on Friday, where he exclusively revealed that he and Bret McKenzie were working on a "little something" for the fans.

"We'd do something," he replied when asked if a Flight of the Conchords reboot was in the works after the HBO series ended in 2009. "We're going to film a little something this year."

"We're going to shoot an hour thing," he added.

Clement, who shut down rumors of a Flight of the Conchords revival in 2014, played coy about whether HBO was involved in the project, and teased that he wouldn't discuss what musical numbers he was working on. Clement and McKenzie's first Flight of the Conchords U.K. tour in seven years kicks off in March, however, featuring all the classics from their show, as well as new material.

"[It is] something," Clement told ET. "That's it."

HBO later confirmed the hour-long Flight of the Conchords special on Jan. 11, which will be taped during their U.K. tour and debuted on the network in May.

For now, Clement is starring on FX's Legion, revealing that fans should be prepared for a "tumultuous" season two when the show returns in March.

"You think it's going to be good, because my [character, Oliver Bird], is out of cryogencis... but it cools down a marriage," he admitted. Things may be "cool" between Oliver and his wife, Melanie (Jean Smart), but Clement couldn't be more jazzed about working with the actress.

"I'm a big fan of Jean from Fargo, season two, so I was excited [to work with her], and I love watching her. I think she's kind of the cast favorite," he gushed. "She's the one everyone loves watching."
